Abstract: A support apparatus for scaling and working on an inclined roof made up of at least one ladder having a pair of ridge hooks to engage the roof ridge, a rotatable support frame secured to the ladder, and a pivotally mounted platform for support of workers and materials. The support frame includes a pair of horizontal members, a pair of vertical legs, and a cross brace assembly, attached to one another by a mechanism adapted to allow rotation of the legs of at least 180 degrees around the outside of the horizontal member from an axle formed by the cross brace. The ladder includes hollow rungs and an opening in each rail forming a tubular passage. Each of the legs have a tube horizontally attached to each end forming an opening for alignment with the ladder openings whereby a securing rod can be passed through the passage. The rod acts as a spindle upon which the legs rest to the outbound sides of the ladder.
